The giraffe of Nairobi National Park: home range, sex ratios, the herd, and food
(University of Nairobi, 1966)
The giraffe of Nairobi National Park, Kenya have been studied for one year. Each animal seen has been photographed from the left side and the pattern on the neck used to recognize each individual. While the pattern may ...
The Palaeomagnetism of some Scottish Tertiary Dykes and their Baked Contacts
(University of Nairobi, 1964)
This paper presents results of measurements of the directions of magnetization of dyke samples and the associated baked sediments collected from Ayrshire in Scotland. The results suggest that these reversely and normally ...
Measurements of total electron content near the magnetic equator
The columnar electron content, nT, has been measured at Zaria for a 9-month period by the ‘close-spaced frequency’ method using the 40 and 41 Mc/s transmissions from the beacon satellite S-66 (BE-B). The ‘diurnal’ variation ...
The belt of equatorial spread-F
(University of Nairobi, 1960)
The morphology of the belt of equatorial spread-F at sunspot maximum is investigated, using I.G.Y. data, for magnetically quiet and magnetically disturbed conditions respectively. The belt is found to extend from about ...
The paleomagnetism of the Turkana lavas
(University of Nairobi, 1966-02)
Directions of magnetizations obtained after cleaning the Miocene lavas from northwest Kenya are presented. The pole position thus obtained, together with similar data from eastern Africa, indicates that no significant ...
Delayed Implantation in an Equatorial Fruit Bat
AT Kampala, Uganda (latitude 0° 20' N.), there is an enormous roost of the fruit bat, Eidolon helvum Kerr. Numbers vary seasonally, with a maximum of about 250,000 during October-November
Equatorial spread-F at Ibadan, Nigeria
(University of Nairobi, 1961)
The characteristics of equatorial spread-F at Ibadan (magnetic latitude 3°S) are investigated including nocturnal, seasonal, solar-cycle and magnetic disturbance variations; and all of these are found to show marked ...
